  • Duplex microphone communication system
    Patent number: 4691349
    Abstract: A full duplex microphone communications system permitting simultaneous bi-directional communications for a two conductor shielded microphone cable. A talkback signal is injected by an encoder at one end using a balanced input to transmit a common-mode signal on the two conductors of the microphone cable using the shield as a ground reference. This signal is then decoded at the other end of the cable by decoding circuitry which covers the common-mode talkback signal.
